Topical OTC use. Benzoyl peroxide is used at 2.5-10% in gels, creams, and washes, applied to acne-prone areas once or twice daily; lower strengths (2.5-5%) are usually as effective as 10% with less irritation. There is no oral or systemic dose — it is not ingested. It is often combined with a retinoid (e.g. adapalene) for greater effect. This library does not provide an ingestion protocol.
